TREATMENT DIRECTED AT SECONDARY SITE â¢When a patient is admitted because of a primary neoplasm with metastasis and treatment is directed solely toward the secondary site, the secondary site is designated as the principal diagnosis even though the primary malignancy is still present.
Secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat. Examples include areas which have been cleared of existing vegetation (such as after tree-felling in a woodland) and destructive events such as fires. Secondary succession is usually much quicker than primary succession for the following reasons: There is already an existing seed bank of suitable plants in the soil. Root systems undisturbed in the soil, stumps and other plant parts from previously existing plants can rapidly regenerate.
